There is a tenth level in Shrapnel City called Tier Drops. To get there, go to the movie
level, and go to the stage with the NASA sign and the body parts with a telescope. Kill
the alien with the chain gun, and press [Use] on the sign. A door should appear with the
caution sign that ends the level. Note: Do not go to the stage with the ship or
this will not work.

If you have a jet pack, fly up and destroy the beer blimp. Guns and health will scatter on
